Let's face it. If you child has persisted this long in speaking only the words, "I am Groot" since watching the Guardians of the Galaxy movie, he's not going to give up his new identity. You could move toward the acceptance stage of this process by getting him this Child Groot Costume to wear. Now he'll look like the character he admires so much, and his new language will seem charming in it's new context.
